Pick the setup that matches your arrival style
An eSIM is usually the fastest option if your phone supports it. Airport kiosks are convenient, while city shops can be cheaper if you are willing to wait.
Whatever you choose, test data access before leaving the seller so you do not waste time fixing connectivity later.
Data matters because many daily services depend on it
Ride-hailing, maps, translation and hotel messaging all become much easier once your connection is stable.
Connectivity is a small setup step that pays off throughout the trip.
